Arp Headbolts + Metal Head Gasket On Mi16 Liners?

[wicked 103 3 Cars]

Currently I'm rebuilding a 1.9 alloy Mi16 engine for low boost application.

Now I've done some searching and read a comment that the alloy of the block itself expands more than the steel liners of the block, if the engine warms up and you need protrusion on the liners to compensate for that.

 

Now I was planning to use a Cometic MLS head gasket and ARP headbolts to avoid a blown head gasket if I put boost on it.

(In a lot of 1.9/alloy block boosted projects I see a pattern of 1 bar boost -> blown head gasket)

 

Is the stress put on the alloy head by MLS head gasket + ARP head bolts not too much (in cold condition), since the ARP bolts are not elastic like the OEM ones? The MLS head gasket might also be less flexible than the OEM one... Or the other way around: is the clamping of the head in hot condition less than with OEM elastic bolts?

 

Does anyone has experience with the combo: alloy block + ARP head bolts + MLS head gasket?

 

(Don't wanna copper head gasket, since I have to replace it too often)

 

Next to that, I've read that some people put sealant on the bottom of the liners? Is that bad practice or an improvement wrt the rebuild manuals that say you shouldn't?
